BigFloat FFT in Julia

votes

I'd like to perform FFT over an array of BigFloats in Julia, but so far I couldn't make it possible. I found FFTW.jl and followed the instructions in their docs (importall FFTW, etc.). Sadly this did not help and I'm still getting ERROR: type BigFloat not supported when running a command like fft([BigFloat(1.0)]).

Did anybody experience (and hopefully overcome) similar issues?

FFTW.jl is a wrapper to the C library FFTW which cannot handle BigFloats. You need to find a pure-Julia code, like this one in FastTransforms.jl.
